"What say you, friend? You seem prepared for work, but I trust there is no cause for fear."

The other looked up sharply at the speaker from under his hood, and went on with his occupation, saying,—

"He that despises his enemy is not wise; he that reviles a people in their own country is not wise; for sands as well as walls may have ears. I cannot talk,—when time serves, I may act. Danger there is, but as for cause of fear,"—and he once more looked at his companion's face, which had waxed paler—"it does not seem required in your case."

The horseman, whose name was Mohammed, galled by the reproof, but not daring to resent it, drove his spurs into his horse, which plunged forward and brought him in contact with the mule's load, a projecting part of which caught the folds of his dress, causing a large rent, and exposing a belt he wore next his person. This did not escape the other's quick eye, though he appeared to take no notice. The moon was a few days old, but the light of a clear, starry sky was sufficient on these white plains, and they travelled on until midnight, when they arrived at some wells, and halted. These wells were of a great depth, and the water was drawn from them in small leathern buckets, and poured into a stone trough, the exhausted camels biting, kicking, and pushing, in their eagerness to reach the coveted fluid. As the camels were watered, their fore knees were tied up, to prevent them straying, and they were turned loose to graze, on what few thorny plants they could find, while the men rolled themselves in their hayks, and were soon asleep, undisturbed by the roaring of camels, the shouts of the drivers, and the confusion which lasted for hours.

At daylight the march was resumed, but the party seemed to have lost their spirits; the song was hushed, and nothing was heard but the vociferations of the drivers, urging on their beasts, while the merchants plodded on silently, their heads enveloped in burnooses and large turbans, as a protection against the sun. About noon they came to a firmer soil, and the guides gave notice that they were approaching the halting-place, while the spirits of all were exhilarated by the prospect of reaching rest and water. Yusuf remembered the warning of the Arab, indicating these wells as the place of danger. About an hour's ride ahead, they could see masses of rock and brushwood on the plain, and when about a mile from this, the man on the spare horse rode forward to borrow a flint to put in his gun; and, whether by accident or design, it went off. A movement was now seen among the rocks, and spears and shining gun-barrels protruding above them, showed the place to be occupied.

"We are betrayed!" ran from mouth to mouth; "A signal!" "Down with the Kafir!" and they surrounded the horseman who had fired the shot. He remonstrated against their quarrelling amongst themselves, but was only met with cries of "Down with him!" "Drag him off his horse!" when, seeing they were determined on violence, he suddenly stripped off his striped cloak and turban, hurling them, with the gun he had fired, far away with his right hand, while his left held his bridle and a short double gun; his blue frock showed him to be an Arab.

"Back, slaves!" he shouted, in a voice of thunder; "I am Ali the Falcon!" and a smile of scorn was on his face, as the crowd recoiled before him, "let wisdom be with you. You thought me in your power—you are in mine—resistance is useless, offer none, and I pledge my word that you shall all return unharmed in person; the word of Ali el Bezz is sacred. Resist, or draw blood,—and may the curse cleave to my father's tents if every soul of this company shall not die this day!"

The crowd were panic-struck; some knew him, and all had heard of his daring deeds and wonderful escapes. The majority, who had not much to lose, were content to save their skins, but the rich merchants were loth to lose their all without a struggle, but were feebly seconded by the soldiers. At this critical moment, a band of thirty or forty horsemen, breaking the silence of the Desert with their united war-cry, "Allaw hu ackbaār!" their guns poised above their heads, rushed down at full speed, through a cloud of dust, on the affrighted travellers, while Ali, overlooked in the confusion, galloped out of the throng, and joined his band, who, seeing no appearance of resistance, had come to a halt.

"You should be more cautious," said Ali to his lieutenant; "not show your teeth before you can bite. You nearly sent me to heaven across the edge of a knife."
